5.What are the limitations of modern periodic table you think? Write in “BULLET POINTS”. An alkaline solution was prepared with LiOH in such a way that 0.65 g dry LiOH was directly mixed with 0.6 M 650 mL LiOH solution and finally 350 mL more water was added to it. Find the final pH of the solution. You need to consider 100% dissociation of LiOH. [Ref: 7Li, 1H, 16O]

- 23. lodide ion (1) is the conjugate base of hydroiodic acid (HI). Why doesn't sodium iodide cause an appreciable increase in the pH of water when it dissolves into Na* and I ions? (a) The Na' is acidic and neutralizes the basicity of I (b) It is a stronger acid than it is a base in water, so Nal actually lowers the pH when dissolved. (c) There are no H₂O* ions present in the solution that could react with I. (d) At least a small amount of HI must be present in order for I to act as a base to raise the pH. (e) HI is a strong acid that reacts completely, which makes I a correspondingly weak base. 24. K, for methylamine (CH3NH₂) is the equilibrium constant for which reaction?

- We have seen an introductory definition of an acid: An acid is a compound that reacts with water and increases the amount of hydronium ion present. In the Chapter on acids and bases, we saw two more definitions of acids: a compound that donates a proton (a hydrogen ion, H+) to another compound is called a Bronsted-Lowry acid, and a Lewis acid is any species that can accept a pair of electrons. Explain why the introductory definition is a macroscopic definition, while the Bronsted-Lomy definition and the Lewis definition are microscopic definitions.arrow_forwardWhat are the equilibrium concentration of H3O+, CN and HCN in a 0.025 M solution of HCN?
